Mechanics and Fixing Any Questions Answered

I think lifetime warranty is supposed to cover manufacturing defects, not "you will never be able to break this forever"...

I thought that too, here's the small print;

Halfords Advanced hand tools come with a Lifetime Guarantee. Should a Halfords Advanced hand tool fail while being used for the purpose and in the manner for which it was designed, it will be inspected and replaced.
Simply return the product to your nearest Halfords store and a store colleague will either order you a replacement, or provide one on the spot. Discontinued items will be replaced with an equivalent product in terms of use and quality.
We replace over 99% of tools that are returned under warranty.
We will replace any tool that is broken, snapped, bent or cracked.
We will only not replace a tool if it has been rusted, burnt, modified or mechanically ground down.
